Basic features
With the series type T we offer a program with several
variants and constructions for the transport of almost
all pumpable media.
It can be used up to maximum rotational speeds of
1500 rpm at pressures up to 16 bar. The rotational speed
is basically determined by the viscosity or lubricity of the
pumped medium.
At viscosities in excess of 10000 mm²/s the medium to
be pumped should flow to the pump. In case of suction
heights of more than 7 m LC and admission pressures in
excess of 2 bar please contact our engineering depart-
ment as larger piping cross sections will be required!
The pumps are driven by electric motors, backgeared
motors, belt drives adjustable gear motors, or similar.
All pumps can operate with clockwise or counter-clo-
ckwise sense of rotation. Please indicate the required
sense of rotation in your purchase order. Slight peaks
may be produced in all pumps with drive shaft positioned
below. Here it must be taken into account that the direc-
tion of delivery flow will change.
Nearly all construction types and sizes of pumps can
be provided with a built-in, adjustable pressure relief val-
ve. We also offer separate pressure relief valves to be
inserted into the pipeline!

Application in ATEX range
We supply gear pumps according to EC-directive
94/9/EC (ATEX 95).
Equipments for zone 1 + 2 (II2G / D T3 und T4), which
ensure a high level of safety. Designed for the case, it is
to be counted on an explosive atmosphere. Shaft seal-
ing (G + GGK) with temperature monitoring.
Equipments for zone 2 + 22 (II3G / D T3), which en-
sure a normal level of safety. Designed for the case, it is
to be counted on an explosive atmosphere rather rarely
and if so, only for a short time. Shaft sealing (P + G)
without temperature monitoring.

NkW = nominal power requirement at the pump shaft related to a viscosity of 50 to 150 mm²/sec (cSt). Subject to change.
The pump capacity (l/min) is related to 500, 700 and 950 1/min. It will be reduced as a function of the rated speed of the motor.
Variation of the delivery output: ±5%.
The pump capacity will also be reduced at a viscosity of less than 50 mm²/sec..
